Application filed November 6, 1924. Serial No. 748,253. I

To all whom it may concern:

Be it known that I, EDD C. OLIVER, acltizen of the United States, andresident of the city of Adrian, county of Lenawee' and State ofMichigan, have invented certain new and useful Improvements in Electro-"plating Racks, of which the following is a. specification, referencebeing had to the accompanying drawings.

Considerable difliculty in the construction of racks for the abovepurpose has heretofore been encountered for the reason that the hangersprovided on the racks for suspending the work to be electro-platedbecome coated and the coating must from time to time be removed. Theremoval of this coating, necessitates the rack being temporarily placedout of use and it is the primary object of my invention to provide arack wherein the hangers are removable so that new hangers may 'besubstituted for used ones, and the rack kept in continuous service.

It is a still further object to provide arack, the vertical portion ofwhich is of" square formation so that the hanger supports may beaccurately )fi-Ild rigidly secured thereto. It is a still further objectupper portion of the rack constituting the hook by which it issuspended, so that one of'the sharp edges of the square will constitutethe contacting surface thereon, ,with the result that a betterelectrical contact may be made by reason of the sharp edge cutting orpenetrating any coating which may have aceuminulated upon thesurface'with which it contacts. With the above, and other objects,my-invention consists in the arrangement, combination and constructionof the various parts of my improved device, as described. inthe squarepiece of conducting material having a vertical portion 5 and a hookportion 6,

the stock being twisted as at 7, so that the sharp edge of one of thecorners thereof tral to twist the.

will constitute the bearing surface in the hook as at 8. p

Secured on thevertical portion 7 are a plurality of cross pieces 9,which may be soldered to the flat surface between the edges of thesquare.

The cross. pieces 9 are provided with a plurality of punched out ears10, one adjacent'each end thereof and one at approximately the centerthereof, the two outer ears extending in opposite directions to thecenear.

A plurality of hangers 11, which ma be pieces of wire having their outerends ent upwardly, as at 12, are secured, one to each of thecrosspiece's 9, bymeans of disposing them between the cars 10 in such amanner that the outer earsprevent movement thereof in one verticaldirection and the central ear prevents movement thereof in the othervertical direction; Thus the hangers are held'securely in lace but maybeeasily and quickly remov' and other like ones sub stituted when it isdesirable to doso.

It is obviousthat'various changes may be made in the arrangement,combination and construction of the various parts of my improved devicewithout departing from the" spirit of my invention, and it is myintention to cover b my claims such changes as may be, reasonablylncluded within the scope thereof.

What I claim is:

1. A rack for use in electro-plating consisting of a vertically disposedmember having laterally extendlng crossieces thereon, and hangersremovably secure to said crosspieces. e

2. A rack for use in electro-plating consisting of a'vertically disposedmember having laterally extending cross-pieces thereon. said crosspieces having punched out ears thereon, some of which extend in onedirection 'aiid others in another direction, a

hanger removably secured by said ears to said cross-pieces. 3. A rackfor use in electro-plating, consisting of a vertically disposed memberhaving laterally extending cross (piece thereon and hangers removablysecure thereto, said vertical member being provided with flat surfacesat the securi g points of said crosspieces.
